SPECIFICATION forming part c1' Letters Patent No. 368,499, dated August 16. 1887. Application filed April 7, 1887. Serial No. 231,030. (No model.)

To all whom it may concern: Be it known that I, RICHARD TEICHMANN, a citizen of the German Empire, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Motors, of which thefollowing is a specification.

This invention relates to improvements in motors for toys and other articles, as set forth in the following specification and claims, and

lillustrated in the accompanying drawings, in

Which--V Figure l is a longitudinal central section of a toy. Fig. 2 is a detail view of an actuator. Fig. 3 is a section in the plane x w, Fig. l. Fig. 4 is an inverted perspective view of part of a toy. Fig. 5 is a transverse section of a modiiication. Fig. 6 is a longitudinal section of a modification. Fig. 7 is an end view of a modiiication.

Similar letters indicate corresponding parts.

In the drawings, the letter A indicates the body of the toy. The body A may have different forms, as desired. For example, in Fig. l is indicated a turtle, and in Fig. 6 a carriage.

B is a wheel, motor, or propeller. An actuator, O, is connected to the propeller B. A simple form of actuator is a band of india-rubber or elastic-material, as indicated in Fig. 2. The actuator is secured to the body A by suitable means-such, for example, as lugs or eyes D, engaging the actuator. Said actuator is also secured to the propeller B. When the propeller B is rotated-kas, for example, in the direction of the arrow shown on the propeller in Fig. lthe rotation of the propeller will twist the actuator to a state of tension. If the toy is then placed on the ground, the rotation of the propeller produced by the tension of the actuator will cause the body A to move. The

propeller is so arranged that it will engage the ground, so as to drive the body A.

A winding device-such as a string or connection, F-is secured to and wound about the propeller B, or about its core or axle, in such a way that when the string F is drawn oft the propeller the propeller is rotated to subject When the string F is released, the tension of the actuator moves the propeller, so as to wind up the string F, and also to propel the body A. The body A is of such weight that when the string F is drawn off from the propeller the propeller will berotated and twist or stretch the actuator. The

actuator can thus be readily wound up or stretched by raising the body A from the ground, grasping the free end of the string, and letting the body A fall to the ground. The descent of the body winds up the actuator.

In place of a string the winding device may be made in the form of lugs F', as seen in Fig. 5, whichlugs can be grasped to rotate the propeller and to subject the actuator to tension. In the drawings, Fig. 5, a pin, E, is shown as securing the propeller B and actuator C, so that the rotation of the propeller will cause tension ot' the actuator.

In addition to the propeller B, the body A may have rotary supports or wheels G, as seen in Fig. 6. By having the body A located above the propeller, so as to surround and conceal the propeller B in whole or in part, as seen in Figs. l and 3, an ornamental appear^ ance of the device can be secured.

In place of the supports G being placed as shown in Fig. 6, the supports G may be placed as seen in Fig. 7-that is, on line with vthe axis of rotation of the propeller B.

In place of an elastic band, C, a spring or springs, O, Fig. 7, can be used as an actuator. The actuator O, in place of being secured to the propeller B by a pin, E, as seen in Fig. 5, can be secured to the propeller by any other suitable fastening device, E, such'as an eye, as seen in Fig. 7. By placing the supports G on the axis of rotation of the propeller the body A can rock or oscillate on the propeller B and on the supports G, which may be desirable in some kinds of toys.

In Fig. l the propeller B is shown as being placed below the center of gravity of the body A, and the orifice or passage in the body A, through which the string F passes, is placed near the center of gravity of the body A. A result of this arrangement is that if the body Ais suspended by the string F said body will bein such position that upon descending to the surface to be traversed the periphery of the wheel or propeller B will be at once caused to come into contact with said surface. The

wheel B thus does not waste any of its power, as would be the case if the wheel B revolved without having its periphery in contact with said surface, in which latter case the wheel B IOO roV

ersed, and the torsional spring located under 'K the body and connected to the body and wheel in line with and parallel to the axle of thelatter, said wheel by rotating in one direction twisting the spring and placing it under torsional tension to propel the wheel and the vehicle-body above it on the surface to be travrersed, substantially as and for the purposes described. l

2. The combination, with a body, A, the propeller-wheels B, and the tubular axle of the propeller-wheels for supporting and moving the body on the surface to be traversed, of a torsion-spring, C, con nected with the body and passing through the propeller-wheels and their axle, and a string or its equivalent conneeted with said axle for rotating the propeller-wheels to vtwist the spring and place it under torsional tension for propelling the body and wheel on the surface to be traversed, substantially as described. a

3. The combination, with a body, A, and a propeller-wheel, B,below the center of gravity of said body for supporting and moving said body on the surface to be traversed, of a torsion-spring connected with the body and propellerwheel in line with and parallel to the axis of said wheel, and a string or its equiva- -lent made to enter a passage at or near the center of gravity of said body, and adapted to rotate said propeller-wheel to twist the spring and place it under torsional tension for propelling the body and wheel on the surface to be traversed, substantially as described.

In .testimony whereof l have hereunto set my hand and seal in the presence of two subscribing witnesses.
